Legend of the Five Rings (L5R) is a set of games set in Rokugan, a land of heroic samurai, mystical shugenja, and fearsome creatures from the Shadowlands. It started in 1995 as a collectible card game (CCG) with a new twist: each new set of cards changed the world, as the cards told the story of the Clan War that ravaged Rokugan. Although the shape of the two-year story arc was roughed out during the original all-night design meeting in February 1995, it left scope for variation so that the game's players could have an effect on that story.
